Hi everyone. I am new here and am really just starting out with epoxy for tumblers. I am trying to find out the best way to fix drips in epoxy on my tumblers. it hasn’t fully cured so how do I fix this. do I wait a couple of days and then try to sand it down even? If so, what grit sandpaper do I use to do that? I still have to put another coat of epoxy on them so Im not too concerned about the “scratches” although I don’t want it to appear through the next coat. Please help
